cm?
Please donot give any irrelevant answer only relevant one

Answer 1

Answer:

BC = 10cms

Step-by-step explanation:

Given,

AP= 4cm

AP=AR -------(tangents from the same point are equal)

therefore, AR=4cm

AC= AR+CR

11=4+CR

therefore, CR= 7cm

CR=CQ--------(tangents from the same point are equal)

therefore, CQ= 7cm

BP=BQ---------(tangents from the same point are equal)

BQ=3cm

BC=BQ+CQ

BC=3+7

therefore, BC=10cms
